HOT-WATER AND ICE BAG CLOSURE 0R STOPPER.

Application filed May 12, 1916.

To all whom 2'2. may concern:

Be it known that I, J OI-IN J. BOWES, Jr., a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have invented new and use ful Improvements in Hot-Water and Ice Bag Closures or Stoppers, of which the following is a specification.

The invention relates to stoppers, and more particularly to the class of quick detachable stoppers for containers such as hot water and ice bags or the like.

The primary object of the invention is the provision of a stopper of this character wherein the employment of screw threads upon the stopper is eliminated and the same is securely locked in the mouth of a container to positively close the same against leakage and to permit the quick detaching of the stopper when the occasion requires.

Another object of the invention is the provision of a stopper of this character wherein the use of a disk washer is dispensed with as the same becomes worn by constant use and by reason of excessive screwing of the ordinary stopper used in hot water and ice bags for the closing thereof to avoid leakage, the stopper being of novel construction for the quick detachment and attachment thereof with despatch.

A further object of the invention is the provision of a stopper of this character wherein the gasket or resilient ring is of a construction to permit the expansion thereof under the action of the contents of the bag or container and thus obviate any poss1- bility of the leakage of the contents from the same when the bag or container is in use.

A still further object of the invention is the provision of a stopper of this character wherein the construction thereof permits the use of a flexible tube for converting the container or bag into a syringe, the tube being positively fastened in the stopper so as to obviate the pulling away of the tube therefrom irrespective of the strain exerted upon the tube A still further object of the invention is the provision of a stopper of this character wherein the same is formed with an outlet bore or passage and carries a removable cap, the bore also being designed to receive a flexible tube which can be readily and easily 5 detachably fastened therein.

provision of a stopper of this character which is simple in construction, thoroughly reliable and eflicient in operation, strong, durable and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplifiedin the construction hereinafter described, and the scope of the application of which will be indicated in the appended claim.

In the accompanying drawings:

Figure 1 is a fragmentary vertical longitudinal sectional View through a hot water bag showing the stopper constructed in accordance with the invention applied;

Fig. 2 is a similar view showing the stopper in vertical sectional elevation;

Fig. 3 is a view similar to Fig. 2 with the cap of the stopper removed and a portion of a flexible tube fastened in the stop- P Fig. 1 is a fragmentary sectional view through an ice bag showing a slight modification of stopper for use therewith, the stopper being partly in section.

Similar reference characters indicate corresponding parts throughout the several views of the drawing.

Referring to the drawing in detail, especially Figs. 1 to 3 thereof, A designates a portion of a hot water bag having the usual neck B and funnel shaped mouth C, and within the neck is received the stopper hereinafter fully described.

The neck is lined with a ring 10 preferably made from metal and formed with external ribs 11 for a portion of its length, which are pressed in or engaged with the internal surface of the neck B for the permanent mounting of the lining therein. \Vhen in place the upper end of the lining protrudes a slight distance within the funnel mouth C as shown. The ring 10 beyond its threaded portion 11 has its internal diameter reduced and the annular shoulder 12 thus provided is flared for a purpose presently described.

Removably fitted within this lining is a stopper whose body 13 is formed with a reduced externally threaded outer end 1 1 for the detachable mounting thereon of a cap 15 which is externally knurled at 16 to permit the quick and easy application and removal of said cap, while on the topof the latter is formed a knob 17 with which loosely engages a ring at one end of a flexible hanger 19, the same being also connected with a tab 20 on the funnel mouth 0 and in this manner the cap is prevented from becoming lost when removed from the stopper body 13, as will be clearly apparent.

The stopper body 13 at its inner end 21 has an external groove 22 providing an end flange 23 and concentrically of this boss 21 and seated within the groove is an expansible packing ring 24. This gasket is of substantially inverted U shape, and the outer wall is of greater width than the inner wall thereof and is adapted to contact with the inner surface of the ring 10 when the stop per body 13 is inserted therein. Thus the liquid contained within the body of the bag A will act upon the outer and inner walls of the depression for expanding the same to assure a fluid-tight joint between the gasket and the stopper body 13, as will be obvious. The stopper body 13 is formed above its groove and gasket with an externally beveled annular shoulder 25 which cooperates with the shoulder 12 internally of the ring 10 when the stopper body 13 is locked in position therein for closing the hot water bag. rojecting from the stopper body 13 at diametrically opposite points thereof are pins26 which are adapted to engage in L shaped slots 27 formed in diametrically opposite points of the ring 10 and opening through the upper edge thereof, the inner ends of the slots 27 being formed with olfset notches 28 forming seats for the pins 26 when the same have been inserted through the open ends of the slots 27 and the stop per body 13 turned within the ring 10 for the engagement of the pins 26 in the seats 28, thereby securely fastening the stopper body in place against accidental removal.

Formed axially through the stopper body 13 is a bore or passage 29 having flared ends 30 and 31 respectively, the end 31 being of greater extent than the end 30, and into either of the same is adapted to be received a hollow truncated conical shaped spreader member 32 which is adapted to be inserted in the end of a flexible tube 33 when passed through the bore 29 for the fastening of the said tube in the stopper body 13 in the flared end 30, as is clearly shown in Fig. 3 of the drawing, the spreader 32 being formed with a looped. handle 34L to permit the convenient application and removal of said spreader to and from the tube 33, it being understood of course that when the tube 33 is inserted in the stopper body 13 it has been previously removed from the ring 10 in the neck of the bag. When the tube 33 is detached from the stopper body 13 the spreader may be placed within the flared end 31 of the bore 29 as is clearly shown in Fig. 2 of the drawing, and the ca 15 will prevent the loss of the said. member held therein.

In Fig. 4 there is shown a slight modification of the invention, wherein D designates a portion of the body of an ice bag having the usual neck E in which is fitted the ring 35 constructed similarly to the ring 10, yet said ring 35 is of considerably greater diameter with respect thereto so as to permit introduction and removal of ice to and from the bag. This ring 35 is also fastened with in the neck E similarly to the ring 10 in the neck 13 of the bag A, and detachably fitted withinthe ring 35 is the stopper which com prises a hollow substantially cup shaped body 36 formed with a reduced inner end 37 having an external channel or groove 38 to receive the expansible gasket 39 which is identical to the gasket 24, and this body 36 is fastened in the ring 35 through the medium of the pins 39 and slots 10 carried by and formed in the body and ring respectively. The body 36 is formed at its outer end with a knurled external bead 41 to permit the convenient application and removal of the stopper, as will be obvious.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the herein described closure will be readily apparent and, therefore,a more extended explanation has been omitted.

Having thus described my invention, I claim:

In abag closure, a liner adapted to be fastened within the neck of the bag and having a bore with smooth portions of two diameters leaving an offset internal annular seating shoulder between them, in combination with a threadless stopper having a portion, the external diameter of which adapts it to fit into that portion of said bore of larger diameter and against said annular shoulder, said stopper also having a portion of smaller diameter formed With an external packing groove, a resilient packing ring seated and held in said groove and formed with an annular channel in that edge thereof which faces toward the interior of the bag and is directly exposed to the pressure of the contents thereof, and means for locking said stopper in said liner.

In testimony whereof I afiix my signature.
